SPRAYING DEVICE Filed Dec. 11, 1935 2 Sheets-Sheet 2 Patented Mar. 23, 1937 UNITED STATES PATENT OFFICE 4 Claims.

My invention relates to spraying devices and particularly to a hand operated device adapted to quickly, economically and thoroughly spray trees, vines, shrubbery, garden plants, buildings, etc.

One object of my device is to provide at a very small cost a means for satisfactorily accomplishing any of the usual spraying jobs encountered on the truck farm, in the garden or vineyard or about the poultry house.

Another object of my invention is to provide a device that can be put into use instantly and without any complicated adjustments or priming.

A further object of my invention is to provide a device that does not clog or get out of order while being used.

And, another object of my device is to provide a sprayer that is easily cleaned after being used.

I have provided a device which accomplishes all of these objects, which has no moving parts,

that is easy to operate and that is adapted to handle any type of liquid spray material.

My device is provided with an adjustable baille plate by which the type of spray stream may be I readily altered to suit existing conditions, providing at will a widely scattered spray or a narrow, restricted spray stream that carries a long distance, thereby enabling the user to spray objects at different distances effectively and thoroughly.

A spray stream having a great deal of force can be produced by my device making it useful for washing cars, windows, etc., and for many other purposes.

The fact that my device is always ready for instant action makes it an ideal instrument for fighting fire.

A more detailed description of my invention is given in the following specifications referring to the accompanying drawings in which:

Fig. 1 is a perspective view of my device.

Fig. 2 is a longitudinal cross section of the sprayer.

Fig. 3 is a vertical cross section taken through the container at ab Fig. 2.

Fig. 4 is a plan view of the baffle plate.

Fig. 5 is a cross section of the baille plate taken on line cd Fig. 4.

Figs. 6, '7, 8 and 9 are diagrammatical views showing how my device operates.

In more detail in Fig. l, l indicates the sidewalls 50 of the container, 2 is the inclined outer end of the container, 5 is the handle, 6 is the outlet opening, 1 is the air intake opening, 8 is the baflie plate held in position by the screw 9 and nut ID. The container is secured to the handle 55 by nails H.

In Fig. 2 the same numerals indicate the same parts as in Fig. l and the numeral 3 designates the inner end of the container while 4 indicates the bottom.

I A vertical cross section through the opening I is shown in Fig. 3.

Fig. 4 is a plan view of the baiile plate 8, showing the slot 8a. which accommodates the screw 9 and which allows the plate to be adjusted to difierent positions. Fig. 5 is a cross section of the plate taken on line cd Fig. 4.

Fig. 6 shows diagrammatically the device being filled by dipping into a bucket containing the spray material l2.

Fig. '7 shows the device at the beginning of the stroke.

Fig. 8 shows the device in an intermediate position and shows how the liquid i2 is forced toward the outer end of the container.

Fig. 9 shows the liquid being forced through the nozzle of the device by its own centrifugal power upon suddenly arresting the circular movement of the device.

In operation my device is dipped into the liquid spray material and filled approximately half full of the liquid or until it contains all it will hold in the tilted position shown. The device is then swung in an arc with the air inlet forward in such a manner that centrifugal force is set up in the liquid and the liquid is pocketed against the bottom and outer end of the container. The swing or throw is directed toward the object to be sprayed and when the device has progressed in the arc to a point where the nozzle or outlet opening is directed toward the object the swing is suddenly arrested, allowing the liquid to continue by its own momentum through the opening in a spray. Air enters the container through the intake opening to displace the liquid.

The spread of the spray may be controlled by manipulation of the adjustable bafile plate. A wider spray is obtained by shortening the extension of the baffle plate, while a narrower stream is produced by lengthening the extension and a still more direct stream is obtained by removing the baiile plate. It will be noted that these adjustments are easily made by loosening the nut on the retaining screw and sliding the baflie to the desired point and secured by tightening the nut or the baflle may be removed entirely without completely removing the screw through the slot provided in the baiile.

I claim:

1. A spraying device comprising a. receptacle for holding liquid spray material, said receptacle having closed bottom, closed sides and closed ends, one of said ends being inclined outwardly at the top, said receptacle having attached thereto and forming a top portion thereof a 5 handled member, one end of such member extending to a point near the top of the inclined end of said receptacle, an outlet being provided between said last named portions and an inlet being provided centrally of said top portion, the opposite end of said handled member extending beyond the said container and forming a handle by which the device may be swung by hand in an arc whereby a centrifugal force is afiorded liquid in said container and whereby upon suddenly arresting the circular movement of said container the liquid is permitted to pass out at the outlet opening in a spray while air is permitted to enter at the inlet opening to replace such liquid.

2. A spraying device comprising a receptacle member for holding spray material, a rigid-outwardly extending handle member attached to said receptable member whereby the latter may be swung in an arc, said receptacle having confiningwalls, one of said walls being designed to constitute the forward wall when the device is swung in an arc and one of its walls constituting the outer Wall, said receptacle having a discharge opening adjacent the outer wall and the forward WalL-said outer wall inclining inwardly from said discharge opening, said forward wall having an inlet opening inwardly of said discharge opening whereby air may enter-the receptacle as spray material is discharged through said discharge 7 opening, said receptacle being designed to retain the spray material while being swung in an arc and'to discharge such material when the arcuate movement is suddenly arrested.

3. A spraying device including a container for holding spray material, a rigid, outwardly extending handle member attached to said container whereby said container may be swung in an arc, said container having a discharge opening in its outer extremity adjacent its forward side as it is swung in an arc, said container having its outer wall inclined inwardly from said discharge opening at such an angle that material in said container will not be discharged while being swung in an arc, but will be discharged upon suddenly arresting the arcuate movement of said container, said forward side of said container having an opening inwardly of said discharge opening whereby air may be admitted to replace the spray material as it is discharged from the container.

4. A spraying device including a container for holding spray material, a rigid, outwardly extending handle member attached to said container whereby said container may be swung in an arc, said container having a discharge opening in its outer extremity adjacent its forward side as it is swung in an arc, said container having its outer wall inclined inwardly from said discharge opening at such an angle that material in said container will not be discharged while being swung in an arc, but will be discharged upon suddenly arresting the arcuate movement of said container, said container having air intake means in cooperative relation with said forward side and located inwardly of saiddischarge opening whereby air may be admitted to replace the spray material as it is discharged from the container.
